The Vertebrate animals they are those endowed with a spine or vertebral column, which divides the body into two identical halves (bilateral symmetry). Normally its body can be divided into the head, trunk (thorax and abdomen) and tail. For example: dog, parrot, toucan, shark.
This classification includes more than 60,000 species current, as well as an important number of fossils, since it is estimated that their evolutionary origin is at the beginning of the period Paleozoic, during the Cambrian explosion. The oldest known is the Haikouichtys, originated 525 million years ago.
With few exceptions, the reproduction of vertebrates It is sexual in nature, and its locomotor, circulatory, respiratory, endocrine, nervous, digestive and excretory systems are among the most complex known.
